Technical Field

[0001] This utility model relates to the field of transfer technology, and in particular to a plate lifting tool. Background Technology

[0002] The raw materials used in the processing of aerospace components are often large aluminum plates and other materials. These raw materials are inconvenient to transfer during processing. The current method of transfer is to put a pair of rope loops on the raw material and then transfer the plate horizontally or vertically. However, this method of transfer has poor safety issues. In addition, when transferring vertically, it is not convenient to accurately place the plate horizontally on the processing table of a large machining center. Utility Model Content

[0003] This utility model provides a plate lifting tool to overcome the shortcomings of the prior art and solve the problem of poor safety during plate transfer, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A plate lifting device includes a long, narrow lifting arm. Two upper rectangular rods, perpendicular to the length of the arm, are fixed to both ends of the lifting arm with screws. First holes are formed on both sides of each end of the upper rectangular rod. Multiple vertical rods pass through the upper rectangular rod, each with an upper cap located on the upper side of the upper rectangular rod. A recessed part is fixed to the lower end of each vertical rod at the same end. A pair of second holes are formed at both ends of each recessed part, and movable rods are movably installed within these holes. A concave moving part is threaded to the upper end of each pair of movable rods at the same end, located within the recessed part. A vertical member is threaded to the lower end of each pair of movable rods at the same end. The lower end of each vertical member is bent inwards vertically to form a hook. Protruding plates are welded to both sides of the upper end of the vertical member, and a connecting shaft is rotatably provided at the other end of each protruding plate. The outer end of the connecting shaft is rotatably equipped with a V-shaped rotating arm. One end of the rotating arm has a third hole along its length, and the other end of the rotating arm has a fourth hole along its length. The vertical member has a fifth hole arranged vertically. A pair of connecting rods are movably installed in the fifth hole. A movable recess is fixed to the outer end of the connecting rod. A through rod is rotatably installed to the outer end of the movable recess. Both ends of the through rod pass through the third hole. A pressing member is fixed to the inner end of the connecting rod. The pressing member is located inside the vertical member. The movable recess is located outside the vertical member. A movable upper rod is movably installed in the first hole. A lifting vertical plate is rotatably installed at both ends of the movable upper rod. A lifting lower rod is rotatably installed at the lower end of the lifting vertical plate at the same end. Both ends of the lifting lower rod pass through the fourth hole. The lifting vertical plate is located outside the upper rectangular rod.

[0005] Furthermore, a V-shaped lifting ring is welded at the middle position of the upper wall of the lifting arm along its length.

[0006] Furthermore, the vertical member and the hook are bent on both sides to form side reinforcing plates, and the root of the convex plate is located on the side reinforcing plates.

[0007] Furthermore, a sixth vertical hole is provided on both sides of the concave moving part, and a dumbbell-shaped connector is movably installed in the sixth hole. Multiple slots are provided at both ends of the concave part, and the connector is engaged in the slots.

[0008] Furthermore, the inner end of the connector is provided with an inner plate, which is located inside the concave moving part. A locking rod is formed on the outer wall of the inner plate, which is locked in the locking groove. An end nut is threadedly connected to the outer end of the locking rod, which is located outside the lower concave part.

[0009] The advantages of the above technical solution are: This invention, through the design of the pressure member and the hook, can support the plate during the transfer and hoisting process by using the hook and the pressure member to press down and constrain the plate. In this way, the plate is in a flat position when it is transferred, and the plate can be prevented from moving during the transfer, thus ensuring safety.

[0010] Features such as slots and connectors can lock the positions of the hooks and pressing parts, while adjustable hooks can be placed on the recessed parts to facilitate adjustment according to the size of the sheet metal. The spacing between the upper rectangular rods can be adjusted by their positions, such as by setting multiple sets of mounting holes on the lifting arm, and adjusting their positions according to the needs of specific applications.

A movable rod 27 is movably installed in the second hole 44. The upper end of each pair of movable rods 27 located at the same end is fixed with a concave moving member 40 by a thread. The concave moving member 40 is located in the lower recess 43. The lower end of each pair of movable rods 27 located at the same end is connected with a vertical member 28 by a thread. The lower end of the vertical member 28 is bent inward to form a hook 30. Side reinforcing plates are bent on both sides of the vertical member 28 and the hook 30. The upper ends of the vertical member 28 are respectively welded with protruding plates 35. The root of 5 is located on the side reinforcing plate. The other end of the convex plate 35 is rotatably provided with a connecting shaft 36. The outer end of the connecting shaft 36 is rotatably provided with a V-shaped rotating arm 37. One end of the rotating arm 37 has a third hole 38 along its length, and the other end of the rotating arm 37 has a fourth hole 39 along its length. The vertical member 28 has a fifth hole 29 arranged vertically. A pair of connecting rods 31 are movably installed in the fifth hole 29. The outer end of the connecting rod 31 is fixed with a movable recess 32. The outer side of the movable recess 32... A through rod 34 is rotatably provided on the side end, with both ends of the through rod 34 passing through the third hole 38. A pressing member 33 is fixed to the inner end of the connecting rod 31. The pressing member 33 is located inside the vertical member 28.
